摘要：
Breeding system (1) for fish belonging to the Cyprinidae family, and more particularly for zebra fish of the species Danio rerio, the said system comprising a breeding tank (2) having a bottom (2a) and side walls (2b), a spawning support (3) placed in the breeding tank (2) and comprising a platform (4) forming a spawning zone positioned a distance away from the bottom (2a) of the breeding tank (2), and a water circulating system (17) configured to modify the water level in the breeding tank (2) and at least partially flood the platform (4) of the spawning support (3), in which breeding system the spawning support (3) comprises a funnel (7) comprising a truncated conical wall (8) having a lower orifice (9) extending near the bottom (2a) of the breeding tank (2) and in fluidic communication with the water circulating system (17) by means of a pipe (11), and an upper orifice (10) extending some distance away from the bottom (2a), the platform (4) being fixed near the upper orifice (10) of the funnel (7), and the breeding system further comprises a removable shut-off member (13) configured to at least partially block off the pipe (11) of the spawning support (3) so as to increase the water level in the breeding tank (2) so as to at least partially flood the platform (4), the shut-off member (13) comprising a pipe at the end of which through-holes are formed, the said pipe having a height that is greater than a distance between the lower orifice (9) and the upper orifice (10).
